Bulimia nervosa is characterized by a loss of control over eating behavior, involving excessive food intake in a short period, followed by compensatory behaviors to prevent weight gain or obesity such as self-induced vomiting, fasting, misuse of laxatives, diuretics, or excessive exercise. Similar to anorexia nervosa, there's an excessive concern with body image and weight gain.
